JOHN SCOTT, OF IILLIMANTIQ ASSIGNOR TO THE VILLIMANTIC LINEN COMPANY, OF HARTFORD, CONNECTICUT.

BOBBIN.

SPECIFICATION forming part of Letters Patent N o. 398,002, dated February 19, 1889.

Application filed July 13, 1888.

Serial No. 279.903. (No model.)

.To all whom t may concern/.-

Be it known that I, JOHN SCOTT, ot' Tillimantic, in the county ot' IVindham and State of Connecticut, have invented certain new and useful Improvements in Bobbins, of which the following is a full, clear, and exact description, whereby any one skilled ,in the art can make and use the same.

My invention relates to the class of devices adapted to serve as a form or spool on which thread or yarn is wound; and the object of my invention is to produce such a spool or bobbin that shall be simple and cheap in construction, and sufficiently strong to warrant its use in the mill, and also for transportaL tion lwith the thread on it.

My invention consists in a cone-bobbin made up ot' a tubular center of paper or like material, a conical base of paper into which the tube extends to a plane near its base, and the braces that unite the tube to the inner surface of the cone; and it further consists in details of the bobbin, as more particularly hereinafter described, and pointed out in the claims.

Referring to the drawings, Figure l is a detail view, in central section, of a cone-bobbin of the prior art. Figi is a detail view, in central section, ot' my improved bobbin. Fig. is a det-ail view, in cross-section, of the bobbin on plane denoted by line :r of Fig. 2.

In the accompanying drawings, the lettera denotes a cone-bobbin as a whole that is made up ot a cylindrical stem, b, and a cone-shaped or flaring base, c, the base and stem being hollow to adapt the bobbin to be placed and held upon a spindle for the purpose of winding yarn or thread upon it into a mass somewhat asvoutlined by the dotted line in Fig. 1. A cone-bobbin has been made prior to my invention of a paper tube joined at the point d to the upper part ot' a paper cone, substantially as illustrated in Fig. l; but such bobbin has never come into use, and has been used only experimentally, for the reason that stem and the cone are made, preferably, of

paper-board, the stem being of sufficientstrength to support the mass ot' Vthread and to stand the wear and handling in use in the mill and of transportation.

The braces 7L h are preferably disk-shaped,

and are so iirlnly secured that they not only hold the cone to the tubular stem or center,

but they also serve in of the cone.

l As a result of this improved constrlletion,

l I am able to produce a bobbin of great strength, lightness, and cheapness that is particularly durable both in use and transportation.

I claim as my invention* l. A spool or bobbin consisting ot a central tube of paper, a conical base otl like material secured to the center, and the disk-shaped crosswise-brace that extends across the lower part of the base and is secured to the tube and the base, all substantially as described.

2. As an improved article ot manufacture, a paper cone-bobbin made up of a central tube of paper, a paper cone into which the said tube extends to a plane near the bottom of the base, and the disk-shaped braces eX- tending transversely of and within the base and securedto the base and to the tube, all substantially as described.
